Optimal Operation of PV-Battery-Diesel MicroGrid for Industrial Loads Under Grid Blackouts. (arXiv:1807.05753v1 [math.OC])

来源于:arXiv
In this paper, we propose an approach to determine the optimal operation strategies for a PV-diesel-battery microgrid covering industrial loads under grid blackouts. A special property of the industrial loads is that they have low power factors. Therefore, the reactive power consumption of the load cannot be neglected. In this study, a novel model of a PV-battery-diesel microgrid is developed considering the active as well reactive power of the microgrid components. Furthermore, an optimization approach is proposed to optimize the active as well reactive power flow in the microgrid for covering the load demand while decreasing the power consumption from the grid, minimizing the diesel generator (DG) operation cost as well as maximizing the consumed power from the PV-array. It has been found that the proposed operation strategy induces a huge reduction of the consumed energy cost and the PV curtailment. 查看全文>>
